How to read this weight chart for boys:

This chart shows weight percentiles, according to the CDC, for boys 6 months of age. To determine an individual's percentile, find the range that includes their weight. This percentile is not a reflection of optimal weight for an individual, it is only for comparing against a population sample. Use the navigation links above the summary chart to view the weight chart for a different age, or to switch between boys and girls or pounds and kilograms.

For people over the age of 20, please refer to our adult height-weight charts. Your body mass index (BMI) is a good indicator of a healthy weight, to find out what your BMI is, and what it means try our calculators page.
